San Diego Leaders in Formosan Termite Control
Steps to Formosan Termite Control
Formosan Termites Established in San Diego
In 2018, Thrasher Termite & Pest Control identified a new colony of Formosan subterranean termites in La Mesa, half a mile from the original 1992 outbreak of this destructive, invasive species. Formosan subterranean termites rapidly develop huge colonies and can cause significant structural damage within 6 months. Even more recent identification of Formosan termite colonies in residential homes as well as undeveloped areas of La Mesa means Formosan termites are now well established in San Diego County. Thrasher Pest is continuing to use the best available treatments for eradicating Formosan termites. At the same time, Thrasher Pest continues to participate in studies to test new treatment methods for Formosan termites. One of the best ways to protect your home is early detection of Formosan termites. For this reason, Thrasher Pest HIGHLY recommends termite monitoring for all structures in La Mesa and the surrounding areas.
Conclusive identification of Formosan subterranean termites was made by Thrasher Termite & Pest Control in cooperation with the San Diego County Department of Agriculture and the California Department of Agriculture Plant Pest Diagnostics Division in Sacramento, California.
